Cheap Autolites.
The photo simply shows the plug killed by detonation. It is not plug quality issue, imo. Nevertheless i love ngk and denso built quality for the ceramics. Too bad too many design patents prevent the super plug sold cheap for masses
NGK Iridiums -- Last forever
Otherwise, whatever is cheap at Walmart...

Yep, that's the car's fault, not the plug. I'm surprised to not see aluminum on the plug. When they get that bad -- it usually "holes" a piston. Get that checked out !!

The car is fine... no oil consumption and runs good. All the other plugs looked good if something did get in there should of took another plug or two with it. Most likely the electrode fractured off and rounded off over time. Not saying those Bosch's are bad.. it happens and I've never seen it with all the different plug brands I've ran over the years.

DENSO`S!
For obvious reasons.
I always use Motorcraft coppers in the Mustang. I've always used Autolites in everything else.

It's usually one cylinder when it happens -- it could be many things. Bad plug wire, bad stick-coil, bad cylinder, etc.
The telltale sign is the color of the insulator -- that insulator is totally white with no brown or black color. Cylinder is running way too hot. It will probably do the same thing with the next plug.
It won't hurt much more to replace the plug, but check the plug after a couple hundred miles and see if the insulator color is the same or darker. If it is darker, then the plug was the problem, if not better get it checked.
If you are not willing to accept that the motor could have mechanical problems, then why did you post the question in the first place? Never rule out the obvious when you are troubleshooting -- that's usually what it is.

I prefer Autolite plugs. They come in regular, platinum and double platinum. I think plugs with the black finish on the metal parts just seem to always be better for me. I once heard of a reason why they were better, but I can't remember why.
I'm kinda all over the place with plugs. I use ACDelco "Rapidfire" (#4's) in my '79 Cadillac because I like to keep it going with Delco parts. Have Bosch in my truck, and Champions in the wife's PT.
NGK V-Power.

Perhaps the black finish is a black-oxide coating that resists corrosion better than the other spark plugs?
I don't know what is used on other spark plugs to inhibit corrosion if anything at all.
Good thing there isn't any road salt where I work.

Answer: AC Delco Professional Iridium
(made and stamped by NGK in Japan)
Comments: I have read enough not to trust Bosch and there +4 designs. There is a new premium one from NGK or Denso ... Laser something which I am interested in.
